moment get time period AM//PM localized

Question

Do we have a function like moment.weekdays() or moment.months() which will return AM PM localized? Something like moment.period()?

timeFormatDefaultLocale({
    "dateTime": "%A, der %e. %B %Y, %X",
    "date": "%d.%m.%Y",
    "time": "%H:%M:%S",
    "periods": ["AM", "PM"], <------ I need to pass moment function to get period
    "days":  moment.weekdays() as any,
    "shortDays": moment.weekdaysShort() as any,
    "months": moment.months() as any,
    "shortMonths": moment.monthsShort() as any
});

@Ankita Jaiswal can you please explain what exactly you required? — Ajinkya, Jun 14 '19 at 06:12
At this point of the code, I don't have the date, I will pass this format to localize the date. — Ankita Jaiswal, Jun 14 '19 at 06:14
@Ajinkya i want something like this: periods : moment.period(). moment.period() this is not a function in moment. I want a function which returns localized AM/PM like for days we have moment.weekDays() — Ankita Jaiswal, Jun 14 '19 at 06:14

Please try with this

 moment.format('A')

here A is for AM PM format

Please refer example bellow :

  console.log('Current Time is :'+moment().format('hh:mm A')) ;

I want method which will return ["AM","PM"]. This will only return AM or PM. – Ankita Jaiswal Jun 14 '19 at 06:30
@Ankita Jaiswal Sorry i am not getting you ? can you please elaborate ? – Ajinkya Jun 14 '19 at 06:40
let AM = moment("05:30:00","HH:mm:ss").format('hh:mm A').split(' ')[1]; let PM = moment("15:30:00","HH:mm:ss").format('hh:mm A').split(' ')[1]; "periods": [AM, PM], Have done like this as workaround – Ankita Jaiswal Jun 14 '19 at 06:54
that's working, but that's a workaround. There should be some standard method which should return this. I am looking for that method. – Ankita Jaiswal Jun 14 '19 at 07:01

There is no built-in momentjs function to get ['AM', 'PM'] localized, if you look at Accessing locale specific functionality section of the docs, you will see that moment has isPM and meridiem:

localeData = moment.localeData()
// ...
localeData.isPM(amPmString);  // returns true iff amPmString represents PM
localeData.meridiem(hours, minutes, isLower);  // returns am/pm string for particular time-of-day in upper/lower case
// ...

Have a look at Customize#AM/PM and Customize#AM/PM Parsing sections to have further info on how moment manages meridiem.

For most of the locales you can write your own workaround function like this one (using moment(Object), format() and locale()):

function period(locale) {
  return [
    moment({h: 0}).locale(locale).format('A'),
    moment({h: 23}).locale(locale).format('A')
  ];
}

['en', 'en-us', 'de', 'it', 'fr', 'zh-cn'].forEach(localeName => {
  console.log( localeName, period(localeName) );
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment-with-locales.min.js"></script>

If you nee to manage also locales that have multiple AM/PM values (e.g. zh-cn), you can use something like the following:

function period(locale) {
  const result = new Set();
  let m = moment({h: 0}).locale(locale);
  for(let i=0; i<24; i++) {
    result.add( m.format('A') );
    m.add(1, 'h');
  }
  return Array.from(result);
}

['en', 'en-us', 'de', 'it', 'fr', 'zh-cn'].forEach(localeName => {
  console.log( localeName, period(localeName) );
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment-with-locales.min.js"></script>

If you consider using other libraries, note that Luxon (momentjs "younger brother") has the Info.meridiems() method that may help you, even if seem to handle always 2 values for AM/PM (See zh-cn result):

const Info = luxon.Info;

['en', 'en-us', 'de', 'it', 'fr', 'zh-cn'].forEach(localeName => {
  console.log( localeName, Info.meridiems({ locale: localeName }) );
});
